Version 1.1
Using cp_bos_updates:

cp_bos_updates -d device

"device" can be a CD or DVD, or a directory.
"device" needs to be a location that has the bos.rte* updates
at the same level as the original operating system install.

NOTE:
bos.rte.tty should be the last update processed.  If you do not
see it at the end of the output, you may need to increase the 
size of the /usr filesystem.   Please check the output.

-------------------------------------------------------------

Introduced in 6100-08 and 7100-02, is the ability for a 
Workload Partition (WPAR) to be upgraded, when restored to a new global system 
that has a different install history (but is at a more recent level of AIX), 
than the global system the WPAR was originally created on.  

For new system installs (overwrite/preservation/migration) of 6100-08 or 
7100-02, cp_bos_updates is run as part of the operating system install.
The log is in /var/adm/ras/cp_bos_updates.log.
Note, when run command line, cp_bos_updates does not save the output
to a log.

For systems installed with prior base levels of AIX, and upgraded to
6100-08 or 7100-02, in order to support WPAR upgrade,
cp_bos_updates must be executed before any restores of WPARs from systems
with a different install history.

The cp_bos_updates command restores the root parts of bos.rte* updates
onto the system, which are then used for the WPAR upgrade.

If your system was base installed at 6100-05 and upgraded to 6100-08,
bos.rte.install install history will be similar to:
  # lslpp -ah bos.rte.install

The cp_bos_updates command needs to be run with a software source (device) from
6100-05.   This can be physical media from 6100-05, or a 6100-05 NIM lpp_source
made from physical media, or from the 6100-05 Technology Level updates
as downloaded from Fix Central or on physical media.

For instance, if I have the TL updates mounted on /mnt/6100-05,
I can run:
  # cp_bos_updates -d /mnt/6100-05

Then for each bos.rte* 6.1.5.0 update, that had a root part, you will
see a 6.1.5.0 directory in /usr/lpp/bos/bos.rte* directories:

  # pwd
  /usr/lpp/bos/bos.rte.install
  # ls   
  6.1.5.0       6.1.8.0
  # ls -R 6.1.5.0
  inst_root
  6.1.5.0/inst_root:
  liblpp.a
  # 

PRIOR to any WPAR upgrade operations, its strongly suggested that
all updates on the global be committed.
